Hi team!
Hoping to get some help with automating part of our workflow - currently when picking up a subtask the assignee has to manually add the task to the board in order to see it in the List view. I’d like to figure out a way to automate this: When an assignee is assigned a subtask, then that subtask is added to the same board as the parent task.
If anyone is able to help that would be appreciated!
Hi @Zabi_Khan , welcome to the forum 
I’m not sure if adding subtasks as normal tasks is the best solution to what appears to be visibility issues you might be facing, but for what it’s worth, you can create a simple custom rule as such:
When a task is assigned, add to the project.
By default, in the rule settings (gear icon in the top right of the rule editor) the option to run on subtasks should be enabled.
A trigger such as when task is assigned or a field is changed, works. But if you try the trigger ‘when task is added to the project’ will not work because the subtask is technically NOT added to the project upon creation.
